#301A9E sits at 250° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 72% saturation and 36% lightness, it reads as a richly saturated, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 48, 26, 158 produces a 11.88:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #301A9E is a clear variant of CSS indigo — about 47 units away from #4B0082. Designers reach for blue hues at this saturation when the brief calls for bold, immediate signal, and at this lightness when they want a present, comfortable mid-canvas voice. On screen the cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
